SDMM Access Types

Once an SMS App has been registered with SDMM, that app will be placed in a specific category based on its primary function. SDMM will manage the incoming SMS messages and handle the message properly for the user based on user settings. Apps will be prioritized by date of install unless set specifically by the user.

Registering the App with SDMM is critical to ensure the app handles the message properly.
